DETAILED DESCRIPTION OF THE INVENTION

The exemplary embodiments are described more fully hereinafter with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity.

It will be understood that when an element or layer is referred to as being “on,” “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like or similar reference numerals refer to like or similar elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, components, regions, layers, patterns and/or sections, these elements, components, regions, layers, patterns and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer pattern or section from another region, layer, pattern or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of an exemplary embodiment.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular an exemplary embodiment only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

An exemplary embodiment are described herein with reference to cross sectional illustrations that are schematic illustrations of illustratively idealized an exemplary embodiment (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, an exemplary embodiment should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. The regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the invention.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Turning now to FIGS. 1 and 2, FIG. 1 is a cross sectional view illustrating a window structure of a comparative example, and FIG. 2 is a plan view of the window structure of FIG. 1. FIG. 1 a cross-sectional view of the window structure of FIG. 2 cut along the line I-I′. In FIG. 1, a camera sensor that may be disposed facing the window structure is also shown.

Referring now to FIGS. 1 and 2, a window structure 50 may include a window 10 and a design layer structure 20 and a light shield layer 30 sequentially stacked on the window 10. The design layer structure 20 may include a first design layer 22 and a second design layer 24 sequentially stacked on the window 10, which is a transparent material, e.g., glass, plastic, etc. The first and second design layers 22 and 24 may have a chromatic color or a white color. The design layer structure 20 may have a first hole 25 exposing a top surface of the window 10. Accordingly, as the design layer structure 20 includes the first and second design layers 22 and 24, the first hole 25 may have a step shape of which a diameter may increase from a bottom portion adjacent to the top surface of the window 10 to a top portion distant from the top surface of the window 10. The first hole 25 may have a circular shape when view from a top side.

The light shield layer 30 may have a black color or a gray color. The light shield layer 30 may have a second hole 35 in fluid communication with the first hole 25, and the second hole 35 may have a diameter larger than that of the first hole 25. The second hole 35 may have a circular shape when viewed from a top side. The first and second holes 25 and 35 may be concentric circles.

A camera sensor 90 may be disposed facing the first and second holes 25 and 35, and the camera sensor 90 may be disposed on a substrate 80. A light that is reflected from an object (not shown) and passes through the window 10 and the first hole 25 of the design layer structure 20 may be incident on the camera sensor 90, and a portion of the light may be reflected from the camera sensor 90 and be incident on the light shield layer 30 and the design layer structure 20. A portion of the light incident on the design layer structure 20 may be reflected again (see rays A1 of FIG. 1) and be incident on the camera sensor 90. Thus, the camera sensor 90 may detect a color of the design layer structure 20 regardless of a color of the object.

If the design layer structure 20 has a very thin thickness, the portion of the light that is reflected from the object, passes through the window 10 and is incident on the design layer structure 20 may pass through the design layer structure 20 (see rays A2 of FIG. 1), and in this case the camera sensor 90 may also detect the color of the design layer structure 20. However, a light that is incident on a portion of the design layer structure 20 covered by the light shield layer 30 may not pass through the light shield layer 30, and thus may not be incident on the camera sensor 90.

As a result, a light having passed through the window 10 may be reflected diffusely at the design layer structure 20 not covered by the light shield layer 30, and the color of the design layer structure 20 that is not related to the color of the object may be detected by the camera sensor 90. Accordingly, the color of the design layer structure 20 may be transferred to surroundings of the image of the object, i.e., a kind of vignette may occur.

Turning now to FIGS. 3 and 4, FIG. 3 is a cross sectional view illustrating a window structure in accordance with an exemplary embodiment, and FIG. 4 is a plan view of the window structure of FIG. 3. FIG. 3 is a cross-sectional view of the window structure of FIG. 4 cut along the line II-II′ of FIG. 4. In FIG. 3, a camera sensor that may be disposed facing the window structure is also shown.

Referring now to FIGS. 3 and 4, a window structure 100 may include a window 110, a first design layer structure 120 and a first light shield layer 130 sequentially stacked on the window 110, and a first light absorption layer 140. The window 110 may be a flat plate, and have a first surface 112 and a second surface 114 opposing the first surface 112. The window 110 may include a light transmission material, e.g., a synthetic resin such as acryl, or glass.

The first design layer structure 120 may be formed on the first surface 112 of the window 110. In an exemplary embodiment, the first design layer structure 120 may include a first design layer 122 and a second design layer 124 sequentially stacked on the window 110. The first and second design layers 122 and 124 may have a chromatic color or a white color. In an exemplary embodiment, the first and second design layers 122 and 124 may have substantially the same color.

The first design layer structure 120 may have a first hole 125 exposing a portion of the first surface 112 of the window 110. In an exemplary embodiment, the first hole 125 may have a circular shape when viewed from a top side. Accordingly, as the first design layer structure 120 includes the first and second design layers 122 and 124, the first hole 125 may have a step shape of which a diameter may increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110. That is, the second design layer 124 may not cover the whole first design layer 122, and thus the first design layer 122 may be partially exposed.

FIGS. 3 and 4 show the first design layer structure 120 having the two design layers 122 and 124 sequentially stacked, however, the first design layer structure 120 may have more than two design layers, and the first hole that may be defined as a sidewall and/or a top surface of the design layers may also have a step shape of which a diameter may increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110. Alternatively, the first design layer structure 120 may have only one design layer. Hereinafter, for the convenience of explanation, only the case in which the first design structure 120 has two design layers will be illustrated.

The first light shield layer 130 may have a black color or a gray color and be formed on the second design layer 124 of the first design layer structure 120, and have a second hole 135 in fluid communication with the first hole 125. In an exemplary embodiment, the second hole 135 may have a diameter larger than that of the first hole 125. The second hole 135 may have a circular shape when viewed from a top side. The first and second holes 125 and 135 may be concentric circles. The first light shield layer 130 may not cover the whole second design layer 124, and thus the second design layer 124 may be partially exposed. Thus, a hole structure including the first and second holes 125 and 135 may have a step shape of which a diameter may increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110.

The first light absorption layer 140 may cover at least a portion of the first design layer structure 120 exposed by the first hole structure, i.e., the first and second holes 125 and 135, and may have a third hole 145 exposing a portion of the first surface 112 of the window 110. That is, the first light absorption layer 140 may cover a sidewall of the first design layer 122, a portion of a top surface of the first design layer 122 and a sidewall of the second design layer 124, which may be exposed by the first hole 125 or may define the first hole 125, and a portion of a top surface of the second design layer 124 exposed by the second hole 135. The third hole 145 may be formed within the first hole structure consisting of the first and second holes 125 and 135 and may have a diameter that is smaller than that of the first hole structure. In an exemplary embodiment, the third hole 145 and the first hole 125 and/or the second hole 135 may be concentric circles when viewed from a top side. In an exemplary embodiment, the third hole 145 may have a sidewall substantially perpendicular to the first surface 112 of the window 110. That is, the first light absorption layer 140 may have a sidewall substantially perpendicular to the first surface 112 of the window 110.

In an exemplary embodiment, the first light absorption layer 140 may cover not only a portion of the first design layer structure 120, but also a sidewall of the first light shield layer 130, which may be exposed by the second hole 135 or may define the second hole 135, and a portion of a top surface of the first light shield layer 130 adjacent to the second hole 135. A boundary of the first light absorption layer 140 may be a circle, and the first and second holes 125 and 135 and the boundary of the first light absorption layer 140 may be concentric circles. In an exemplary embodiment, the first light absorption layer 140 may have a top surface substantially parallel to the first surface 112 of the window 110. The first light absorption layer 140 may have a black color or a gray color. In an example embodiment, the first light shield layer 130 may have a gray color and the first light absorption layer 140 may have a black color.

In FIG. 4, the first design layer structure 120 and the first light shield layer 130 cover entirely the first surface 112 of the window 110 except for the first to third holes 125, 135 and 145, however, the first design layer structure 120 and the first light shield layer 130 may be formed only at a portion of the first surface 112 of the window 110 adjacent to the first light absorption layer 140 according to a desired design.

A camera sensor 190 may be disposed facing the third hole 145, and the camera sensor 190 may be disposed on a substrate 180. Accordingly, the third hole 145 may serve as a path through which a light reflected from an object (not shown) may pass.

A light that is reflected from the object and passes through the window 110 and the third hole 145 may be incident on the camera sensor 190, and a portion of the light may be reflected from the camera sensor 190 and toward the first design layer structure 120, the shield layer 130 or the first light absorption layer 140. However, the first light absorption layer 140 may cover portions of the first design layer structure 120 exposed by the first and second holes 125 and 135, and thus light reflected off the camera sensor 190 may be blocked from being incident on the first design layer structure 120 by the first light absorption layer 140 and the first light shield layer 130. Thus, the color of the first design layer structure 120, which may be chromatic or white, may not be detected by the camera sensor 190.

Even though the first design layer structure 120 may have a very thin thickness, a light that is reflected from the object, passes through the window 110 and the first design layer structure 120, and is incident on the first hole 125 or the second hole 135 may be absorbed by the first light absorption layer 140, so that the light may not be incident on the camera sensor 190. A light that passes through the window 110 and is incident on a portion of the first design layer structure 120 covered by the first light shield layer 130 may also be blocked by the first light shield layer 130, so that the light that interacts with first design layer structure 120 does not reach camera sensor 190.

Accordingly, the color of the first design layer structure 120 that is not related to the color of the object may be prevented from being incident on the camera sensor 190, and the vignetting, i.e., the color of the first design layer structure 120 that would otherwise be transferred to surroundings of the image of the object, may be prevented.

Turning now to FIG. 5, FIG. 5 is a plan view illustrating a window structure in accordance with an exemplary embodiment. The window structure may be substantially the same as that of FIGS. 3 and 4, except for the boundary of the light absorption layer 140. Thus, like reference numerals refer to like elements, and detailed descriptions thereon are omitted herein.

A window structure 100 may include a window 110, a first design layer structure 120 and a first light shield layer 130 sequentially stacked on the window 110, and a second light absorption layer 142. In an exemplary embodiment, the second light absorption layer 142 may have a rectangular shaped boundary.

The window structure 100 may have other types of boundary, e.g., an ellipse, polygon, etc., except for the circle or the rectangle of the first and second light absorption layers 140 and 142, respectively. Hereinafter only the window structure having the boundary of circle will be illustrated for the convenience of explanation.

Turning now to FIGS. 6-13, FIGS. 6, 8, 10 and 12 are cross-sectional views illustrating a method of manufacturing a window structure in accordance with an exemplary embodiment, and FIGS. 7, 9, 11 and 13 are plan views of the window structure thereof. More specifically, FIGS. 6, 8, 10 and 12 are cross-sectional views of the window structure of FIGS. 7, 9, 11 and 13, respectively, cut along the line III-III′ of FIGS. 7, 9, 11 and 13. FIGS. 6 to 13 show a method of manufacturing the window structure of FIGS. 3 and 4, however, these may not be limited thereto.

Referring now to FIGS. 6 and 7, the window 110 may include a light transmission material, e.g., a synthetic resin such as acryl, or glass. The window 110 may include a first surface 112 and a second surface 114 opposing the first surface 112.

The first design layer 122 may be formed on the first surface 112 of the window 110. In an exemplary embodiment, the first design layer 122 may be formed by a screen printing process using a mesh. That is, a mesh (not shown) for forming a desired pattern may be mounted on the first surface 112 of the window 110, ink may be sprayed or dropped onto the mesh, and a rubber plate may press the sprayed or dropped ink to form the first design layer 122 having a desired pattern. In an exemplary embodiment, the first design layer 122 may be formed using ink of a chromatic color or a white color, and a metal powder, e.g., silver powder may be included in the ink.

In an exemplary embodiment, the first design layer 122 may be formed to include a first hole 125 therethrough. The first hole 125 may have a circular shape when viewed from a top side. A drying process may be further performed after the first design layer 122 is printed on the first surface 112 of the window 110.

Referring now to FIGS. 8 and 9, a second design layer 124 may be formed on the first design layer 122. The second design layer 124 may be formed by a screen printing process using a mesh as with the first design layer 122. In an exemplary embodiment, the second design layer 124 may be formed using chromatic or white ink, and may be formed using ink having substantially the same color as that of the first design layer 122.

In an exemplary embodiment, the second design layer 124 may be formed to have a hole therethrough. The hole in second design layer 124 and the first hole 125 may be concentric circles. Thus, the hole in second design layer 124 may be in fluid communication with the first hole 125.

In an exemplary embodiment, the hole in second design layer 124 may be formed to have a diameter larger than that of the first hole 125 in order for the second design layer 124 may not be formed on a portion of the first surface 112 of the window 110 exposed by the first hole 125 during the screen printing process. Thus, the first design layer 122 may not be completely covered by the second design layer 124, and a portion of the first design layer 122 adjacent to the first hole 125 may be exposed.

Hereinafter, the first hole 125 through the first design layer 122 together with the hole through the second design layer 124 in fluid communication therewith may be referred to as the first hole 125. A bottom of the first hole 125 may be defined by a portion of the first surface 112 of the window 110 not covered by the first design layer 122, and a sidewall of the first hole 125 may be defined by a sidewall and the exposed portion of a top surface of the first design layer 122, and a sidewall of the hole in the second design layer 124. Accordingly, the first hole 125 may have a step shape of which a diameter may increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110.

The first and second design layers 122 and 124 may define a first design layer structure 120. As described above, the first design layer structure 120 may instead be formed to include more than two design layers sequentially stacked, or may not include the second design layer 124 but include only the first design layer 122.

Referring now to FIGS. 10 and 11, a first light shield layer 130 may be formed on a top surface of the first design layer structure 120, i.e., on a top surface of the second design layer 124.

The first light shield layer 130 may be formed by a screen printing process using a mesh as with the first and second design layers 122 and 124. In an exemplary embodiment, the first light shield layer 130 may be formed using black ink or gray ink.

In an exemplary embodiment, the first light shield layer 130 may be formed to have a second hole 135 therethrough. The second hole 135 may have a circular shape when viewed from a top side. In an exemplary embodiment, the second hole 135 and the first hole 125 may be concentric circles. Thus, the first and second holes 125 and 135 may be in fluid communication with each other.

In an exemplary embodiment, the second hole 135 may be formed to have a diameter larger than that of the first hole 125 so that the first light shield layer 130 may not be formed on the portion of the first surface 112 of the window 110 exposed by the first hole 125. Accordingly, the second design layer 124 may not be completely covered by the first light shield layer 130, and a portion of a top surface of the second design layer 124 adjacent to the first hole 125 may be exposed.

Hereinafter, the first hole 125 together with the second hole 135 in fluid communication therewith may be referred to as a first hole structure. A sidewall of the first hole structure may be defined by the sidewall of the first hole 125, the exposed portion of the top surface of the second design layer 124 adjacent to the first hole 125, and a sidewall of the first light shield layer 130. Thus, the first hole structure may have a step shape of which a diameter may increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110.

Referring now to FIGS. 12 and 13, a first light absorption layer 140 may be formed on the first surface 112 of the window 110 to cover at least exposed portions of the first design layer structure 120 exposed by the first hole structure, i.e., the first and second holes 125 and 135, and thus the window structure 100 may be manufactured.

The first light absorption layer 140 may be produced by a screen printing process using a mesh as with the design layers 122 and 124 and the first light shield layer 130. In an exemplary embodiment, the first light absorption layer 140 may be formed using black ink or gray ink.

In an exemplary embodiment, the first light absorption layer 140 may have a circular shape when viewed from a top side, and may have a third hole 145 exposing a portion of the first surface 112 of the window 110. As described above, the first light absorption layer 140 may instead be formed to have other types of shape, e.g., an ellipse, polygon, etc.

In an exemplary embodiment, the first light absorption layer 140 may cover at least the sidewall of the first design layer 122, a portion of a top surface of the first design layer 122 and a sidewall of the second design layer 124 that may be exposed by or defining the first hole 125, and a portion of a top surface of the second design layer 124 exposed by the second hole 135. Further, the first light absorption layer 140 may cover a sidewall of the first light absorption layer 130 exposed by or defining the second hole 135 and a portion of a top surface of the first light shield layer 130 adjacent to the second hole 135.

The third hole 145 may be formed within the first hole structure to have a diameter smaller than that of the first hole structure, and the third hole 145 and the first hole 125 and/or the second hole 135 may be concentric circles. In an exemplary embodiment, the third hole 145 may be formed to have a sidewall substantially perpendicular to the first surface 112 of the window 110. That is, the first light absorption layer 140 may have a sidewall substantially perpendicular to the first surface 112 of the window 110. In an exemplary embodiment, the first light absorption layer 140 may be formed to have a top surface substantially parallel to the first surface 112 of the window 110.

In particular, a third hole 145 of the third light absorption layer 144 may have a diameter that may gradually increase from a bottom portion adjacent to the first surface 112 of the window 110 to a top portion distant from the first surface 112 of the window 110. Thus, an amount of light that may be reflected from an object, pass through the window 110 and be incident on the camera sensor 190 may be relatively increased.

Referring now to FIG. 15, a window structure 100 may include a window 110, a first design layer structure 120 and a first light shield layer 130 sequentially stacked on the window 110, and a fourth light absorption layer 146. The fourth light absorption layer 146 may have a curved sidewall that forms various oblique angles with respect to the first surface 112 of the window 110. Furthermore, a top surface of fourth light absorption layer 146 is curved and is therefore not parallel to the first surface 112 of the window 110.

Referring now to FIG. 16, a window structure 100 may include a window 110, a first design layer structure 120 and a first light shield layer 130 sequentially stacked on the window 110, and a fifth light absorption layer 148.

The second light shield layer 132 may include a black printed layer or a gray printed layer. The second light shield layer 132 may cover the first design layer structure 120, and thus light may be prevented from being diffusely reflected at the first design layer structure 120, so that vignetting may be prevented. That is, the second light shield layer 132 may serve as both the light shield layer 130 and the first light absorption layer 140 of the window structure illustrated in FIGS. 3 and 4.

Turning now to FIGS. 22 and 23, FIGS. 22 and 23 are cross-sectional views illustrating window structures in accordance with another example embodiment.
